CHARLES LEE, OF ASTORIA, ILLINOIS, ASSIGNOR OF ONE-HALF TO AIVILLIAM SCRIPPS, OF SAME PLACE.

STAPLING- SPECIFICATION forming part of Letters Patent No. 640,781, dated January 9, 1900.

Application filed May 12 1899.

To all whom t may concern:

Be it known that I, CHARLES LEE, a citizen of the United States, residing at Astoria, in the county of Fulton and State of Illinois, have invented a new and useful Machine for Repairing Harness, of which the following is a specification.

The invention relates to improvements in machines for repairing harness.

The object of the present invention is to improve the construction of harness-repairing machines and to provide a simple and comparatively inexpensive one capable of being easily operated and adapted to unite the ends or portions of a broken piece of harness without materially affecting the flexibility of the same by the use of transversely-disposed staples.

- A further object of .the invention is to provide a machine of this character which will be adapted to operate on and adjacent to boxloops without destroying or closing the same.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective vieuT of a harness-repairing machine constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional View on line 3 3 of Fig. 2. Fig. 4 is a detail perspective view of the loop-holder. Fig. 5 is a detail view of the plunger.

Like numerals of reference designate corresponding parts in all the figures of the drawlngs.

l designates a frame provided at its bottom with a base plate or fiange 2, adapted to be secured to a bench or other suitable support, and the said frame is composed of a lower portion or anvil 3 and an upper arm or portion 4, which curves over the anvil or lower portion and terminates in a guide 5. The

lower portion 3, which is adapted to receive the work to be operated on, is hollow to form a casing, and it is slotted or bifurcated at the guide for the staple.

serai No. 716,565. N0 modem bottom to receive an operating-lever 6, which is fulcrumed on a bolt 6i. The inner end of the operating-lever is curved, as shown, and it engages a head or block 7, provided with a recess 8 at its 'lower face to receive the lever. This cross head or block 7 is provided at its upper face with a stud 9 to receive the lower end of a coiled spring 10, and it is capable of vertical movement in a vertical opening 11 of the frame, and the vertical opening has its upper portion contracted to receive a springactuated staple-supporting bar 12, which is adapted to engage the workand to form a The lower end of the spring-actuated bar or block 12 is reduced at 13 to receive the upper end of the coiled spring, which presses the said bar or block upward and which is also adapted to return the oper#- ating-lever to its initial position.

The spring-actuated or spring-pressed staple-supporting block or bar 12 is provided with a longitudinal slot or groove 14, which is T-shaped in cross-section to enable it to receive a staple 15 and to permit the same to Y be placed in position with its connecting portion or head either longitudinally or transversely of the anvil portion of the frame, whereby the staple may be driven into a strap transversely or longitudinally thereof. The groove 14 also receives a vertically-movable plunger or follower 16, having a Ilange at its upper portion to fit in the transverse portions of the T-shaped groove and adapted to be engaged by the stud of the cross head or block 7 when the lever is operated, whereby the sides Yor prongs of the staple will be driven through the work. When the plunger or follower is in its lowermost position, there is suficient space between its upper end and the upper face of the spring-pressed block or bar to4 receive the staple, and as staples of different sizes are constructed of the same width various sizes of staples may be employed in the repairing-machine.

, The legs of the staple are upset or clenched against the work by being forced against a vertically-adjustable bar 17, mounted in the guide 5 of the arm 4 of the frame and pro vided at its rear face with notches or teeth 18, adapted to be engaged by a pivoted catch or dog 19, mounted in a slot or bifurcation of the arm 4, as clearly illustrated in Fig. 2 of the accompanying drawings, and adapted to hold the bar 17 against upward movement.

' The lower end of the bar is grooved or recessed to present slightly inclined or curved faces to the ends of the staple to bend the sameinward, and the catch or dog i9 is mounted on a pivot 20.

The staples are upset against the bar 17 when ordinary straps or pieces are united, and when working on a. box-loop or adjacent to the same a loop-support 2l is employed. A substantially L-shaped gage 22 is provided for use, so that the Work may be properly placed on the anvil portion of the frame. One arm 23 of the gage is rounded and extends transversely ot the anvil portion of the frame or casing, and the other arm 24:, which is arranged at one side of the frame, is provided with a longitudinal slot 25, through which passes a bolt 26, having a clamping-nut 27, adapted to secure the gage at any desired adjustment. The gage is adapted to be raised and lowered, and it may be moved backward and forward to bring the transverse arm in the desired position relative to the staple-re.

ceiving slot.

The loop-holder, which is substantially U- shaped, is composed of upper and lower horizontal arms 28 and 29 and a vertical connecting portion at the outer ends of the arms. The upper arm 2S is provided with a rectangular opening or eye 30 to receive the lower portion of the bar 13, and the lower arm 29, which is adapted to extend through a boxloop 30, is arranged adjacent to the strap to which the box-loop is secured, so that a staple may be driven through the strap or straps and the ends of the loop W ithout being forced through the top of the latter. The lower arm of the loop or holder is provided with a groove or recess to facilitate the upsetting or clenching of the staple. After the staple has been placed in the groove of the spring-pressed bar and the Work placed on the anvil portion of.

the frame the bar i7 is moved downward and pressed upon the work, being locked in such position by the pivoted catch or dog, and the springactuated har or block will engage the lower face of the Work and hold it lirnily in position While a staple is bein g forced through it.

The invention has the following advantages: The harness-repairing machine, which is simple and comparatively inexpensive in `constrnction,is designed for the use of farmers and various other persons, and it will enable an unskilled person to unite readily the ends of a broken strap or portion of a harness by means of a staple, which will not affect the flexibility of the broken part like arivet. The loop-supporting device is adapted to enable a box-loop to be stapled Without driving the staple through the upper or outer portion of the loop.

Changes in theiorm, proportion, size, and the minor details ot construction within the scope of the appended claims may be resorted to without departing from the spirit or sacriiicin g any of the advantages of this invention.
